If (S)-glyceraldehyde has a specific rotation of -8.7°, what is the specific rotation of (R)- glyceraldehyde? A) -8.7° B) +8.7° C) 0.0° D) cannot be determined from the information given

Answer: B) +8.7°

Explanation: The specific rotation of a chiral compound is a physical property that is characteristic of its stereochemistry. Enantiomers, which are mirror images of each other, have specific rotations that are equal in magnitude but opposite in sign. Since (S)-glyceraldehyde has a specific rotation of -8.7°, its enantiomer, (R)-glyceraldehyde, will have a specific rotation of +8.7°.
